Crescendo Clock - an ESP32 based alarm clock to wake up gently
RP-Pico C library for DS3231 RTC module.
An alarm clock is done with RTC in STM32F103R6 board. It is simulated in proteus.
This library enables you to use RTC from RTL8720-based boards such as RTL8720DN, RTL8722DM, RTL8722CSM. This RTL8720-based RTC, using Interrupt, has no battery backup. Time will be lost when powered down. To need NTP-client to update RTC every start-up.
ESP32 OLED alarm clock that syncs with Google Calendar.
Open Home Security gateway running on STM32F4x7. To replace old, or to create new home burglar alarm using standard commercial PIR, microwave, smoke sensors and reed switches. Includes home automation integration.
AVRlarm is an open source alarm system for 8-Bit Atmel CPUs (ATmega2560).
Tiny embeddable sensor→history→alarm engine in C99. Zero dynamic allocation. Runs on bare metal.
ATmega128 project for digital clock operation
This repository contains the code for a comprehensive security system based on IoT nodes with ESP32 microcontrollers. It consists of master and slave nodes, along with a mobile application for remote control. The system detects intrusions via motion and door sensors, activates alarms, and provides a user-friendly interface for managing security.
GPIO Zone IO Control System
Deterministic, heap-free C99 alarm state-machine core for embedded firmware (on/off delays, latching, shelving, ack) with snapshot/persist support, tests, and CMake.
The most epic NeoPixel based alarm clock
Alarm app for PSP (WIP)
motion detection kiosk for dahua cameras
